Computer-Assisted Instruction (CAI): The basic of digital electronics experiment by use Multisim 10.0 program. Can make the learner get know about the character and the property of a Multisim 10.0 program. And get know about program this instruction in digital alarm test of the integrated circuit (IC) that have the basic of logic gate and at get from logic gate combination such as Inverter (NOT Gate), AND -Gate, OR Gate, NAND Gate, NOR Gate and Exclusive OR Gate. Moreover still get know about the way writes logic circuit and test signal logic from the algebraic equation as well.
